A. The Cisco ONS 15310-MA is a fully redundant, fully protected 6-rack-unit (6-RU) Multiservice Provisioning Platform (MSPP) optimized for metro access networks. It uses the same management interface - the Cisco Transport Controller - as the Cisco ONS 15454, ONS 15600, and ONS 15310-CL platforms, and is fully interoperable with these platforms. The Cisco ONS 15310-MA provides superior circuit scalability (DS-1, DS-3, EC-1, and Ethernet options at both Layer 1 and 2), and includes Small Form-Factor Pluggable (SFP)-based optics capable of OC-3, OC-12, OC-48, and CWDM/DWDM options, plus a wide variety of protection options for up to 99.999 percent reliability.

Q. What unique benefits does the Cisco ONS 15310-MA offer?

A. The Cisco ONS15310-MA bridges the gap between the Cisco ONS 15310-CL and the Cisco ONS 15454 platforms, providing a small-size aggregation and transport solution. It offers higher density, more features, and greater flexibility than the Cisco ONS 15310-CL, as well as fully redundant common equipment and facility protection for a carrier-class, 99.999 percent availability solution. While it has less capacity than the Cisco ONS 15454, it is designed with a smaller footprint and lower price. The Cisco ONS 15310-MA uses the same feature-rich and innovative software as the other optical products in its product family.

Q. What are the physical dimensions of the Cisco ONS 15310-MA?

A. The Cisco ONS 15310-MA is 6-RU (10.5 inches) tall, 10.67 inches wide, and 12.0 inches deep. It fits easily into a 19-inch rack, and two can be mounted side by side in a 23-inch rack.

Q. What are the physical components that make up the Cisco ONS 15310-MA?

A. The Cisco ONS 15310-MA basic product offering consists of the following components:

• Shelf Assembly (MA-SA) supports one fan tray and filter, plus four feature slots, two common control slots, and two backplane interface cards.

• Backplane electrical interface card (EIA-HD-A and EIA-HD-B) - Required for electrical interface and interconnection of DS-1s, DS-3s, EC-1s, to "A" or "B" side of chassis. Accommodates up to 84 DS-1s and three DS-3/EC-1s per chassis side.

• Backplane filler (BP-COVER-A and BP-COVER-B) - blank backplane filler for use when EIA is not installed.

Q. What is the minimum hardware configuration required for the ONS 15310-MA?

A. The minimum equipment required for the Cisco ONS 15310-MA consists of a chassis, fan tray, filter, one CTX card with SFP optics, one CTX filler card, four expansion-slot filler cards, and two backplane covers, if EIA cards are not installed.

Q. What are the power requirements of the Cisco ONS 15310-MA?

A. The Cisco ONS 15310-MA installation requires the use of ground cable, #6 AWG stranded copper conductors for grounding, and #14 AWG stranded copper conductors for power. Use of a 15-ampere (A) fuse is recommended. The system operates between -40.5 volts (V) and -56.7V DC. A typical configuration would draw about 300 watts (approximately 6.5A DC at -48V).

Q. Does the Cisco ONS 15310-MA support redundant power supply?

A. Yes, the Cisco ONS 15310-MA has the following power characteristics:

• Redundant terminal blocks are used for connecting power, and inputs are on the back of the sub-rack with "A" and "B" at opposing corners.

A. The Cisco ONS 15310-MA operates on -48V DC power, and there is no optional AC power input. If only AC power is available, the Cisco AC/DC power rectifier (part number CSCO-ACDC-SYS) can be used for an effective DC power solution.

A. The IP address resides on the controller card, and comes with the default IP address of 192.168.1.2.

Q. How is the Cisco ONS 15310-MA managed?

A. The Cisco ONS 15310-MA uses both Cisco Transport Controller and Cisco Transport Manager Version 7.0. Cisco Transport Controller is a simple Java-based GUI that works via IP. Because other Cisco ONS platforms use this same GUI, the convenience of full management, alarm monitoring, and A-Z provisioning are available from anywhere in the network. Other industry-standard management interfaces such as Transaction Layer 1 (TL1), Simple Network Management Protocol (SNMP), and Common Object Request Broker Architecture (CORBA) are also supported.

Q. Does the Cisco ONS 15310-MA operate on the same software coding as other Cisco optical products?

A. Yes, the Cisco ONS 15310-MA operates on the same software code as the ONS 15310-CL, ONS 15454, and the ONS 15600.
